Public bug reported:
Binary package hint: network-manager
Hello,
in our university environment there are many Xirrus WiFi Arrays that each have
4 or 8 access points integrated. So the client sees many APs and has to choose
one.
In Ubuntu 9.10 and 10.04 the Network Manager is constantly roaming and
disconnecting/reconnecting, and often it doesn't even succeed to get an
IP address. Sometimes it works for a while, then it roams to another AP
and suddenly IP connectivity is interrupted although I'm associated and
still have an IP address. This often can only be corrected by turning
off and on the wireless switch on the notebook.
This does not happen with WICD on Ubuntu (uses wpa_supplicant, too), or
with networkmanager on SuSE. So I think the networkmanager in Ubuntu is
the problem.
Attached is the daemon.log showing the problems.
Driver and hardware information:
- Intel PRO/Wireless 5300 AGN
- iwlagn module
- kernel 2.6.32-22 (but with versions from Ubuntu 9.10 and with recent
linux-wireless-patches, too)
- eduroam wireless network with WPA2 and 802.1x (TTLS)
** Affects: network-manager (Ubuntu)
